As may be used in a positive displacement pump system, a capped stuffing box assembly includes a stuffing box mountable to a discharge tee to prevent pumped fluid from escaping collection via the discharge tee. The stuffing box is capped by a drain cup that may be releasably mounted to the stuffing box and fixedly mounted to a drive pump motor frame, the drain cap having a drain port to communicate leakage upon failure or pre-failure of the seals in the stuffing box. Upon such failure, the stuffing box may be removed from the drain cap and replaced, while alignment between the actuating rod, drive motor, pump actuator, and drain cap is maintained.
